Middlaware await

[tw-hedgehog]

Hi,
should react-router await for middleware to finish before rendering route?
Strange this is if I have even empty loader - router waits for middleware to finish. if there is no loaded then middleware is not awaited.

I use data router.

Use case is to fetch current user information and redirect if session expired or something else.

example: https://stackblitz.com/edit/github-3mlupejh?file=src%2Fapp.tsx

let router = createBrowserRouter([
  {
    path: '/',
    middleware: [
      async () => {
        await new Promise((r) => setTimeout(r, 5000));
      },
    ],
    hydrateFallbackElement: <div>loading....</div>,
    // loader: () => {}, // middleware is awaited only if this is uncomented
    children: [{ path: '', element: <div>test defered rendering</div> }],
  },
]);
